The Ohio Student Edition is identical to the National Student Edition [ISBN: 0131339966] except it contains additional pages (Ohio Mathematics Student Handbook) in the front of the book with Workouts (practice pages) for Ohio Standards Mastery.
Might seem a bit strange to review a textbook, but having gone through this page by page on my own and doing the problems, I'm determined to use this (and the next in the series) for a homeschool curriculum.
This book begins with the absolute basics of algebra by introducing the concept of a variable in an equation. This marks the first step out of arithmetic and into algebra. If one reads the examples and the lessons they've laid out, one would see that concepts are introduced at a very slow and careful rate, only to then ramp up a bit by introducing one more or two more things one at a time, all to converge into one final lesson that makes use of all things introduced in a chapter or a section.
One of the things I really loved about this, was it gave a pretty simple problem to write your own function based on the behavior of Sierpinski's Triangle. While doing this assignment, people may not realize that they are dealing with a fractal and a concept that'll later be introduced in calculus, a limit. Although it doesn't make mention of it, for those curious and eager to think of the "why" behind the assignments, it rewards you with some more advanced concepts.
I'd highly recommend this textbook for those who would love to use it to help teach their kids or for those who want to review and relearn some math they've forgotten.
